43-tooth big bevel gear for center differential is machined from unique HUDY metal material that's been especially developed for gear-type products, also hardened and precision ground to accommodate the tightest tolerance demands for perfect fit with the diff outdrives. The gears are separately machined on a precision German gear unit and every gear is independently tested, inspected, and run in. The diff gear will soon be laser etched with 43T for simple and easy immediate recognition.
Our unique heat treatment makes kit very difficult and strong not merely on the surface but in addition in the core, thus give you the gear an extraordinarily-long lifespan with really low wear comparing to standard gears.
